Objectives: The aim of this study was to examine the effects of electroacupuncture(EA) at the H(7) (Shinmun) on normal humans using power spectral analysis. Methods: EEG power spectrum exhibit site-specific and state-related differences in specific frequency bands. In this study, power spectrum was used as a measure of complexity. 32 channel EEG study was carried out in 9 subjects (9 males; age=25,8 years). Results: In alpha band, the power values at Fp2 channels(p<0.05) during the H7-acupoint treatment significantly were decreased. In beta band, the power values at Fp1, Fp2 channels(p<0.05) during the H7-acupoint treatment significantly were decreased. In delta and theta band, the power values at the H7-acupoint treatment significantly was increased than the before-acupuncture treatment. Conclusions: This results suggest that electroacupuncture at the H7 is significantly in beta band of EEG.
